4.10.8 Remote output function (REM signal, Pr. 495 to Pr. 497)
You can utilize the on/off of the inverter's output signals instead of the remote output terminal of the
programmable controller.

Specifications differ according to the date assembled. Refer to page 330 to check the SERIAL number.

˜
The output terminal can be turned on/off depending on
the
Pr. 496 or Pr. 497 setting. The remote output
selection can be controlled on/off by computer link
communication from the PU connector or RS-485 port
or by communication from the communication option.
˜
Set "96" (positive logic) or "196" (negative logic) in any
of
Pr. 190 to Pr. 196 (output terminal function selection) ,
and assign the remote output (REM) signal to the
terminal used for remote output,
˜
When you refer to the left diagram and set 1 to the
terminal bit (terminal where the REM signal has been
assigned) of
Pr. 496 or Pr. 497 , the output terminal turns
on (off for negative logic). By setting 0, the output
terminal turns off (on for negative logic).
Example)When "96" (positive logic) is set to Pr. 190 RUN terminal function selection and "1" (H01) is set to Pr. 496 ,
the terminal RUN turns on.
ON/OFF example for positive logic
˜
When Pr. 495 = "0 (initial value), 10", performing a power
supply reset (including a power failure) clears the REM signal
output. (The ON/OFF status of the terminals are as set in
Pr.
190 to Pr. 196
.) The
Pr. 496
and
Pr. 497
settings are also "0".
When Pr. 495 = "1, 11", the remote output data before power
supply-off is stored into the EEPROM, so the signal output at
power recovery is the same as before power supply-off.
However, it is not stored when the inverter is reset (terminal
reset, reset request through communication).
(See the chart on the left)
˜
When Pr. 495 = "10, 11", the signal before reset is held even an
inverter reset is made.
REMARKS
˜
The output terminal where the REM signal is not assigned using any of Pr. 190 to Pr. 196 does not turn on/off if 0/1 is set to the
terminal bit of Pr. 496 or Pr. 497 . (It turns on/off with the assigned function.)
˜
When the inverter is reset (terminal reset, reset request through communication), Pr. 496 and Pr. 497 values turn to "0". When Pr.
495 = "1, 11", however, they are the settings at power supply-off. (The settings are stored at power supply-off.) When Pr. 495 =
"10, 11", they are the same as before an inverter reset is made.
CAUTION
˜
When
Pr. 495
="1, 11"(remote output data retention at power OFF), connect R1/11 with P/+, and S1/L21 with N/- so that the
control power is retained. If you do not take such a step, the output signals provided after power-on are not guaranteed.
